<H3>Shortcuts:</H3>
   <BLOCKQUOTE>
      Key macro <I>space</I> implements the command <B>defaults</B>.
   </BLOCKQUOTE>

<H3>Usage:</H3>
   <BLOCKQUOTE>
      <B>defaults</B> <BR><BR>
   </BLOCKQUOTE>

<H3>Summary:</H3>
   <BLOCKQUOTE>
      The <B>defaults</B> command reverts the scale and angle
      settings of the view to the default values.  The default
      scale fits the layout to the size of the 3D viewing window.
      The default rotation is a view from directly above the
      layout, which matches the view in the layout window.
   </BLOCKQUOTE>

<H3>Implementation Notes:</H3>
   <BLOCKQUOTE>
      <B>defaults</B> is implemented as a built-in <B>wind3d</B>
	window command in <B>magic</B>.  It can only be invoked from
	a window created with the <B>specialopen wind3d</B> command,
	or the <B>render</B> procedure.  Note that the <B>wind3d</B>
	window is only available when magic is compiled with the OpenGL
	graphics option and invoked with <B>magic -d OGL</B>. <P>
	
      Note that macros of the <B>wind3d</B> window are hard-coded,
	and cannot be changed with the <B>macro</B>, <B>gmacro</B>, or
	<B>imacro</B> commands.  There is no "<TT>:</TT>" macro for
	entering commands; to enter commands from the command-line,
	use the <A HREF=../tk_path_name.html> <I>tk_path_name</I></A>
	command.  The default Tk path name of the <B>wind3d</B> window
	is "<TT>.magic3d</TT>".
